A TOP city school official was on scene at the notorious "School of No" in Queens, Monday, to investigate shocking conditions, first exposed by The New York Post on Sunday, as angry parents and a City Council member demanded answers.

"Every day, my son tells me all they do is watch TV all day long. I teach him how to read, but this school has not helped him at all. All they do is yell at the kids. I ask them why they are always yelling and the teachers say they have to because the principal is so strong on them," griped Ivelisse Lantigua, 39, whose son is a second-grader at PS 106 in Far Rockaway.

Sources said that fur-loving principal Marcella Sills has an abysmal attendance record and history of uncaring and bizarre behaviour, The Post reported.

"The PTA has problems with the principal. My wife is the vice president of the PTA. The principal, she doesn't care. She dodges parents. She says she's busy but then she's just standing around, and always ready to leave," said Jonathan Pelaez, 26, who was dropping off his daughter for pre K.

"What was reported … is unacceptable, and if true will be immediately addressed," Farina said in a statement.

Sills arrived around 7:30am.

"She hasn't shown up that early in six or seven years," a source said.

And Michael Duvalle, the treasurer of Community Education Council 27, said Sills didn't even bother showing up at their last meeting, when plans for improving the school were on the agenda.

"The principal is going to have to do a better job. She never showed up at the last Community Education Council meeting which is formally the school board. I had her paperwork ready for her and I was waiting. I called her before and she still never showed up," said Duvalle.

Queens Borough President Melinda Katz called the charges disturbing.

"We hope to find out information about what's going on with the kids. Clearly the allegations are disturbing but we are going to find out information now about what's going on," Katz said.

The school became known as the "School of No" because it provides no gym, no art classes, no textbooks covering the Common Core standards and no proper nurse's office.

And Sills forced fifth-graders to pay about $110 apiece for a formal end of year party at which the principal makes them dress up in tuxes and gowns.

The girls must rent little white dresses that look like bridal gowns, and the boys must rent tuxedos with tails, sources told The Post.

"It was bizarre. My daughter told me 'The principal wants us to dress like this. We have to,' " said Luz Nunez, 43, about her older daughter, who has since graduated. She also has a son Brian, 6, and daughter Liz, 9, at PS 106.

Queens City Councilman Donovan Richards was at the school Monday morning, as well, waiting to speak with Deputy Chancellor Dorita Gibson, who was dispatched by Farina to investigate.

"We are very concerned about what is going on in this school. Our children deserve to have quality education. Today we are here to make sure that our children are not being cheated from learning. We want to make sure that they can succeed," Richards said.

Staff described PS 106 as a dysfunctional campus with rat-infested instruction trailers.

Richards said he planned to meet with Gibson after her inspection.

"We will see what the new administration that has come in is going to do with this," said Richards, who met with angry parents at the school before classes Monday morning.

"I think that based on what I've heard today there's a lot of work to be done," he said.

The kids, many of whom live below the poverty line, must foot the bill for the strange get-ups, which Sills personally picks out at stores such as Men's Wearhouse and David's Bridal, parents and ex-teachers said.

Sills, meanwhile, sets herself up as the belle of the ball - donning her own long, white bridal-type gown for the event, which was held last June at Russo's on the Bay in Howard Beach. Last year, her strapless, white getup came complete with elbow-length white gloves, witnesses said.

"It's absurd," said one former teacher at the crumbling Far Rockaway school.

"This is a school where children are given a free breakfast and free lunch, and you're asking them to pay money for a lavish, unnecessary event."

As the school put on a yearly formal ball, kids don't have basic school necessities. "Some children didn't have materials because their parents couldn't afford them," a former teacher said. "It was a struggle and a fight to get crayons, pencils and a notebook."

Sills could not be reached for comment.

Sills is a frequent no-show at the school or arrives hours late. Last week, she missed every school day but one. Nevertheless, she managed to rule in absentia through fear and retaliation, sources said.

She cuts quite a figure, when she does appear. She arrives in a BMW wearing expensive fur coats. She makes a base $128,000 salary. "She's evil," former PS 106 teacher Patricia Walsh said. "She finds pleasure in ruining people's lives."

"She's been getting away with it for years," said Silaka Cox, an NYU freshman who graduated from PS 106 on Sills' watch.
